A Hammond man faces 10 years to life in prison after a jury found him guilty of various drug and firearms charges in federal court this week.

In May 2012, the Tangipahoa Parish Sheriff’s Office found a gunshot victim outside Roy’s Lounge in Hammond. When law enforcement reviewed the lounge’s surveillance recordings, they saw Melvin Jackson, now 34, take a handgun from his waistband and hand it to the shooter, according to a criminal complaint filed by Special Agent Chad Scott, of the Drug Enforcement Administration.

The alleged shooter, Marvin Dokes, is still awaiting trial in Tangipahoa Parish, U.S. Attorney spokeswoman Anna Christman said.

Law enforcement also found drugs in Jackson’s possession during a separate investigation, Christman said.

According to his indictment, Jackson, also known as Melvo, was involved in selling heroin beginning sometime before January 2012 until August 2013, when he was arrested. The weapon and drug charges both went before a federal jury in New Orleans this week.

The jury convicted Jackson on Tuesday on one count each of conspiracy to distribute over 1 kilogram of heroin, possession with intent to distribute heroin and felon in possession of a firearm, the U.S. Attorney’s Office wrote in a news release.

According to Jackson’s indictment, he was convicted in 2007 in the 21st Judicial District on attempted second-degree murder.

He faces sentencing Aug. 12 and, according to the U.S. Attorney’s Office, faces a maximum penalty of life in prison.
